I don't use the LVL brand but with Lash Lift, as long as the solutions are applied at the base of the lashes where the lift happens, 1/3 or 1/2 way doesn't really matter. I have a step by step on here somewhere that covers lash lifting that may help. Sounds like you are pulling the lashes too far up the shield, or the shield isn't being placed close enough to the lashline, and this is causing the eyelid to curl back slightly.
But I am astounded if a reputable company like Nouveau, are only showing students a video rather than the trainer doing a practical demo? Have I picked that up correctly?
